Not, but we're working on it. There's a patchset that needs to be
backported from a more recent kernel to the 4.5 kernel used in the
aarch64 release. Additionally, there are a couple bugs in the kernel to
be fixed regarding memory handling. The RPI3 is limited enough in ram
that these bugs would have serious implications when running the 64bit
version. In short, I hope to have something we can use in the coming
weeks, but it's not currently in a functional state.

One final note: There's a bug in the upstreamed graphics driver that has
significant problems. Because of that, the patchset we're working on
disables it. The distro would be limited to framebuffer console on the
rpi3 only in 64bit mode.

Oh, see  answer above. I answered a bit out of order it seems.
